Title: Digital data rate converters
IPC: H04L25/05
Filed: 1975-03-26
Abstract: 1479313 Data transmission; speed changing MARCONI CO Ltd 26 March 1975 [2 April 1974] 14529/74 Heading H4P A bit rate converter for transmitting data at a rate higher than incoming comprises means dividing lower bit rate incoming data into determined word length which are stored then read-out at a higher rate and means for detecting the difference in rates and inserting padding words of fixed length into the output stream such that the padding words fill the gaps. The higher rate may be independent of the lower and data word length may be the same as the padding word, which can contain information regarding the position of the next following padding word. 60 kHz bipolar data applied at terminal 2 is converted to binary form by converter 1 which also synchronizes oscillator 3; this drives serial/parallel converter 4 dividing the data into 8 bit words, also word counter 6 through a ¸8 dividing circuit 5. Counter 6 outputs specify the next location of a store 7 to be filled, content of which is monitored by 8, also recording clock rates. Parallel/serial converter 10 is driven at a transmitting frequency of 64 kHz causing data words to be read-out of store 7 at this higher rate which is also detected by 8 from which difference in rates is determined. When a counter 15, clocked at word rate 8 kHz is full, it is reset and an enabling signal passed to padding word generator 16, selector 9 and counter 14; the word developed by 16 depends on an input from 8 which specifies for example whether the next padding word will be found after 14, 15 or 16 information words, counter 15 being given a start position depending on the number of words. At insertion periods counter 14 is inhibited for one word. If input and output clocks are in relative synchronism, content of store 7 will remain substantially constant hence generator 16 may produce a coded signal of 0001 to counter 15 hence provide a reset signal after 15 words have been transmitted. If the transmitting clock is running relatively slowly, store 7 will tend to fill hence the signal passed to counter 15 will be 0000 hence will reset every 16 words. Conversely if store 7 is tending to empty then 0010 is passed to 15 hence insertion will be after only 14 words. The receiver, which is approximately a "mirror image" of a transmitter has a counter (26), Fig. 2 (not shown), receiving the coded signal specifying the position of the next padding word and provides on reset this information to a device (24) which arrangement avoids error in case an information word should fortuitously contain the same sequence as padding words. The receiver also includes a frequency control (31) thus ensuring that store (23) neither completely fills nor empties.

Abstract: 1,203,393. Moulding conical bearings. MINISTER OF TECHNOLOGY. 18 March, 1969 [26 March, 1968], No. 14588/68. Heading B5A. [Also in Division F2] Bearing members having frusto-conical surfaces are made by machining a bearing surface on one of the members, casting bearing material against the surface to form a bearing surface which adheres to a second bearing member and separating the members. The machined bearing surface may be treated to prevent the bearing material adhering to it. A frustoconical male member 10 having an accurately machined surface 14 is mounted on a shaft 12 on which is coaxially mounted a female member 11 having a conical recess 15, there being a P.T.F.E. bush 13 disposed between the shaft and the female member. The surface 14 of member 10 is coated with silicon wax and a resin 19 is poured into the conical recess. The male member is moved along the shaft in the direction A causing the resin to fill the space between the members. The thickness of the layer of bearing material is determined by the end face 16 of the member 10 abutting the bush 13. A sleeve 17 is slid along the outside of the female member to shear off any excess resin, and engages with the flange 18 of the male member to align the bearing members. After the resin has set the male member is removed, the bush 13 replaced by a spacer 22 and the male member is replaced on the shaft, the bearing clearance being determined by the length of the spacer. The resin may be an epoxy resin which may contain aluminium oxide and carbon fibres. The cast bearing surface may be provided with grooves, in which fluid may be pressurized during operation of the bearing, by casting the bearing material between the female member and a member identical with the male member except that it has on its surface a raised pattern corresponding to that of the groove pattern required, this member being replaced, after the material has set, by a member having a smooth surface.

Filed: 1934-05-15
Abstract: 424,996. Selectors responsive to code signals. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Byrnes, I. F.; 6171, Liebig Avenue, Riverdale, New York, U.S.A.) May 15, 1934, No. 14671. Convention date, May 25, 1933. [Class 40 (iv)] A selector responsive to a signal comprising a succession of dashes each of approximately four seconds duration separated by intervals of approximately one second includes a thermionic valve having a resistance-reactance timing circuit connected to the grid, potential being applied across the circuit on the occurrence of a dash so that a relay in the anode circuit operates provided the dash endures for a minimum period determined by the timing circuit. In Fig. 1, relay 1 energizes on the receipt of a dash and closes charging circuits for condensers C1, C2 in series respectively with resistances R1, R2. After 3¢ seconds, provided relay 1 remains up, the grid potential of the valve 8 is such as to allow relay 5 to operate in the anode circuit, and the stepping magnet 10 advances its switch arm one step. After 4¢ seconds, should relay 1 be still up, relay 4 operates in the anode circuit of the valve 7 and restoring magnet 11 is effective. Assuming that the dash is of correct duration, relay 5 on relapse closes a charging circuit for a condenser C3 in series with a resistance R3, and if relay 5 remains back for 5 seconds, i.e. if the interval before the next dash exceeds 1¢ seconds, relay 6 operates in the anode circuit of the valve 9 and connects up the restoring magnet 11. After three correct dashes, the switch arm has advanced three steps and an alarm 12 operates. In Fig. 2, relay 33 energizes on the receipt of a dash and closes a charging circuit for a condenser C4 in parallel with a resistance R3. After 3¢ seconds, provided relay 33 remains up, relay 25 operates in the anode circuit of the valve 22 and connects up the stepping magnet 10. After 4¢ seconds, should relay 33 be still up, relay 24 overcomes the spring tension of its armature and operates in series with relay 25, connecting up the restoring magnet 11 (off-normal springs 28 being operated). Relay 32 energizes in parallel with the stepping magnet 10 and upon relapse closes a charging circuit for a condenser C5 bridged by a resistance R4. If relay 32 remains back for 5 seconds, i.e. if the interval between dashes exceeds 1¢ seconds, relay 26 operates in the anode circuit of the valve 23 and connects up the restoring magnet 11. After three steps of the switch arm, relay 27 operates and closes the alarm circuit. A reset button when pushed releases relay 27 and operates the restoring magnet 11. Fig. 3 shows an alternative form of timing circuit comprising a resistance and an inductance connected to the grid of a valve.

Abstract: 1,139,806. Forging. DAVY & UNITED ENG. CO. Ltd. 29 March, 1966 [7 April, 1965], No. 14810/65. Heading B3H. In the forging of a workpiece 21 carried by a manipulator 12 moving at a constant pro-set speed, the press cycle is initiated automatically when the manipulator has moved through a distance corresponding to the desired bite. The manipulator is driven along rails 10 by a variable speed hydraulic motor 8 as described in Specifications 874,909 and 1,011,774 and its peel 20 is movable relatively to the manipulator carriage under hydraulic control as described in Specification 1,015,711. The forging press 14 is driven hydraulically and controlled as described in Specification 1,114,234. Movement of the manipulator along its rails 10 produces pulses from a pulse generator 22, which pulses are passed to a counter 23 and compared in a coincidence unit 24 with the desired bite preset by means 25. When this bite is reached a signal is passed along line 26 through gate 30 to the press control 27 for initiating a new press cycle. Simultaneously a re-set signal is passed along line 28 to the counter 23. If the manipulator moves through the desired bite before the press crosshead 16 reaches its upper limit, the gate 30 remains closed to prevent initiation of the next press cycle. Gate 30 is only opened by a press signal along line 31. If coincidence occurs before the reset counter signal on line 28, due to the manipulator speed being set too fast, a signal is passed by gate 33 to line 34 for stopping both the manipulator and the press. Reference has been directed by the Comptroller to Specification 947,863.
